MACHINE FOR CLEANING HOLLOW ARTICLES.

To all whom it may concern:

Be it known that we, GUsTAvE P. DEL- BAUVE and JOHN W. Fox, citizens of the United States, and residents of Elwood, county of Madison, and State of Indiana, have invented a certain new and useful Machine for Cleaning Hollow Articles; and wepdo hereby declare that the following is a full, clear, and exact description thereof, reference being had to. the accompanying drawings, in which like numerals refer to like parts.

The object of this invention is to improve the construction andoperation of machines for cleaning hollow cylindrical articles such asglassware.

One feature of said machine consists in the means for simultaneously cleaning the interior and exterior of hollow glassware. Also means is associated with the foregoing arranged to frictionally engage and clean the external surfaces of the bottoms of tumblers and the like. A main padded belt cleans the external. peripheries of the glassware. More rapidly rotating cleaners enter the glass and bearit down on said belt. At the same time the glass articles are conveyed through the machine at a speed slower than the travel of saidbelt or the rotation of said internal cleaners. By reason of the padded belt traveling faster than the glassware is moved through the machinev In the drawings, Figure 1 is a rear elevation of the machine. Fig. 2 is a plan view thereof. Fig. 3 is an elevation of the righthand end of Fig. 1. Fig. at is a fragmentary perspective view including cleaning members and means for conveying and operating the internal cleaner. Fig. 5 is a vertical section through a portion of the belt,

a glass article being cleaned and the internal cleaner. I

There is shown herein a frame substan tially rectangular having uprights 10,11 and 12, side bars 14, end bars 15 and 16,

and lower horizontal brace bars 17. The

particular constructionof the frame is not very material and it can be modified as desired.

The machine is for the purpose of clean- I ing simultaneously all of the surfaces of glass tumblers 20 or other hollow glassware, such as lamp chimneys, tubes and the like. The three sections orcleaning members are shown in Fig. 4, namely, the belt cleaner 21 which travels horizontally and lengthwise article 20 is placed by the operator'on one of the internal cleaners 22 at the upper lefthand corner of the machine as shown in Fig. l, and before it reaches the belt 21.

This is repeated for each of the large number of internal cleaners 22 as they come up to the upper side of the machine. Therefore, these glass articlesare conveyed successively longitudinally of the machine and over and in frictional engagement with the cleaning belt 21 and against the bottom cleaner 23. The internal cleaners 22 clean the interior surfaces, the belt 21 cleans the external peripheral surfaces and the pad 23 cleans the external surface of the bottom,

if the article has a bottom. The interior st cleaners 22 are of smaller diameter than the tumblers or other glass articles and they are mounted so as to press the tumbler down hard on the cleaning belt,21 which is supported on the underside.

belt 21 is faster still faster-so that although the conveying movement and rotation of the internal cleaners is in the same direction as the movement of the pad 21, the glassarticle rotates in the direction opposite tothe movement which would naturally be imparted to it by the cleaning belt 21.; This win all appear fromvthe following explanation of details of the mechanism. a The bottom cleaning pad 23' is secured stationarily and longitudinally of the ma- Y chine upon thefront top side bar' 14 and extends for the major portion of the length of the machine by adjustable brackets 24, as seen in Fig. 2. The cleaning belt 21 is The conveying 90 speed of't'he machine is relatively slow. The

, movement ofthe cleanin and the rotation of the lnternal cleaner is somewhat longer than the pad 23, as shown in Fig. 2, and has mounted at each end upon suitable drums 39, end bearings which are secured upon the shafts 26 and 27, see Fig. 2. The shaft 26 is short and one end is mounted in a suitable bearing, not shown,

in the front side of the frame, and the other end in a bracket 28 secured to across bar 29 of the frame, see Fig. 2. Power is applied to the shaft 27 for driving said belt 21 through a pulley 30 thereon, belt 31, pulley 32, belt 33 and motor 34. The upper portion of the cleaning belt 21 is supported in its upper position by a plate 35 secured rigidly to the frame so that the upper portion of the cleaning belt is solid and resists downward movement as the glass articles shown in Fig. 1, travel over the sprocket wheels 44 and 45, one at each end of the machine and driven through the latter sprocket wheel 45, see Fig. 3, on a shaft 46. The sprocket wheel 45 is driven by a pulley 47 on the outer end of the shaft 46, a belt 48, and a pulley 49 on a shaft 50 at the lower part of the machine. The shaft 50 is driven by a gear 51 on sa-idshaft 50, see Fig. 1, and a gear 52 on a shaft 53, and saidv shaft 53 is driven by a pulley 54 and belt 55 running from a pulley 57 on a shaft 58 on which the pulley 32 is secured, see Fig. 1. By this means the glass articles are conveyed on through the machine.

' At the same time that the glass articles and the internal cleaners 22 travel over the machine, said brushes are rapidly rotated by a sprocket wheel 60 secured on said shaft 40, see Fig. 4, that is driven by a sprocket chain 61 operating in a corresponding groove in*a frame 62, whereby said chain 61 is held from" sagging. The weight of the sprocket chain "*42 on the shaft 40 will hold the sprocket wheels 60 into' operative engagement with the chain 61 and force the glass tumbler} down tightly against the cleaning belt 21.; The chain 61, as seen in Fig. 1 travels on sprocket wheels 63 and 64 and is driven by said sprocket wheel 64 since it is mounted on a shaft 65 carried by a bracket 66 andhaving a pulley 67 A belt 68 extends from the pulley 67 to a pulley 69 on the shaft 27. Hence, the belt 31 Which drives the pulley 30 also drives the belt 68 in the direction shown, whereby the chain 61 travels in a direction opposite to the other reaches the bottom cleaning pad 23. The f machine is constantly operating so that the glass article is carried by the internal cleaner 22 over and in engagement with the cleaning belt 21 and the bottom of the glass tumbler engages the pad 23. When the glass tumbler has reached the righthand end of the.

by another operator.

The gearing is preferably such that there will be a difference in the speeds of said parts, varying as desired, but to illustrate this feature of the invention, in-the machines machine, it has been cleaned and is removed which have been operated, the belt 21 travels about 180 feet'per minute, the conveyer means for moving the glass articles and the internal cleaners 22 across the machine, travel about 45 feet per minute, While the internal cleaners rotate about 320 revolutions a min ute. The result is that the internal cleaners bear down on and frictionally engage the lower internal surfaces of the glass articles, cleaning the same and pressing tightly down on the cleaning belt 21 and because of the difference in speed, the glass articles revolve in the opposite direction from what they would naturally revolve by means of frictional engagement of the belt 21. Hence,

the direction of rotation of the glass article is det'erminedby the rotation of the internal cleaner, in spite of belt 21. Since the glass article revolves in a direction opposite to the belt 21, the cleaning action of said belt on the glass article is greatly enhanced. The bottom which bears against the pad 23 moves horizontally and also rotates so that this combined movement cooperates in cleaning the bottom and since there is such strong. frictional engagement between the pad 21 and the glass article also, the glass article does not rotate nearly as fast as the cleaner inside so that the cleaning action is thereby effected.

By the Word cylindrical as used in the claim herein, is meant a hollow article which is substantially cylindrical so that it can be treated by this machine or according to the principle of operation of this machine. Therefore, the invention covers a machine capable of treating, in the manner herein set forth, hollow articles which are hexagonal The invention claimed is: In Witness whereof, we have hereuntoaf- 10 A machine for cleaning hollow cylindrical fixed our signatures in the presence of the articles including a movable external cleaner, witnesses herein named. an internal cleaner adapted to travel in the 5 same direction as and immediately above the ggf ai gx external cleaner and at a slower speed, and.
